Analytical Industries Palm O2 D Oxygen Analyzer - Manual (Page 6)

Procedure
Calibrate: (a) with a known source of dry air,
21% or 100% oxygen before using each day
or after 8 hours of continuous use; (b) when
the temperature or pressure of the operating
environment changes; (c) if the oxygen sensor has
been disconnected and reconnected; (d) after the
battery or oxygen sensor has been replaced.
1. Expose the sensor to the calibration gas (refer
to preceding section) for approximately 30 sec-
onds to allow the sensor to stabilize.
2. Continue exposing the sensor to the calibration
gas until the calibration routine is complete.
3. Press and hold the CAL pushbutton for three (3)
seconds to initiate the calibration routine.
4. The LCD displays CAL, top right, during the
calibration routine which takes 15-20 seconds.
5. The software determines from the sensor’s
signal output whether the device is being cali-
brated with 100% or 21% oxygen.
6. If the calibration is successful, the LCD will
display, middle and bottom right, the oxygen
value of the calibration gas and returns to the
SAMPLING mode.
7. Remove the calibration gas and begin sampling.

Calibration Fails
If the calibration fails, the LCD will display ERR as
illustrated.
An unsuccessful calibration can be caused by
several problems with the sensor, calibration
gas or electronics. Dropping the device will
damage the sensor and electronics.
Do not proceed until corrective action is taken
and the device is calibrated successfully.
If after three (3) unsuccessful attempts to
calibrate: review section 7 for possible causes and corrective action or
contact Advanced Instruments Inc. at 909-392-6900.
4.5 Mounting
The device can be mounted to a 1” diameter pole or a book shelf using the
optional Dovetail Mounting Kit (P/N A-3675-1) and Dovetail Female Clamp Pole/
Shelf (P/N HRWR-1075) as illustrated below.
The dovetail male bracket, top left and middle, is secured to the rear of the
enclosure with one (1) screw and held in place by registration holes molded
into the enclosure.
The 1” diameter dovetail female, top right, clamp pole/shelf is an optional ac-
cessory commonly found in medical applications.
The v-shaped male component simply slides into and out of the pole or shelf
mounted female section.
